This film marks the last one Eille Norwood did as Sherlock Holmes; and apparently as anything else. He died twenty-five years later, but did no more film work. There were two feature films in this series, and about two dozen shorts, done in a two-year period, and the vast majority are lost. What we have, though, reveals a great Sherlock lauded by Conan Doyle himself.
This film is expansive, has a welcome action flow, pretty good settings, appropriate humor, and an unrecognizable plot. Its story line is vastly removed from the book and has some puzzling variations, keeping the viewer guessing at what was happening. Historical value.
